Bring a large pot of salted water to a boil. Add the pasta and cook according to the
package instructions until al dente. Reserve 1/2 cup of pasta water, then drain the pasta
and set it aside.
In a large skillet, heat the olive oil over medium heat. Remove the sausage from its
casing and cook, breaking it up with a spatula, until browned and fully cooked, about 6-8
minutes
Add the pumpkin purée, heavy cream, smoked paprika, nutmeg, chili flakes (if using),
salt, and pepper to the skillet with the sausage. Stir well and let the sauce simmer for
about 5 minutes. If it gets too thick, add a little reserved pasta water to thin it out.
Add the drained pasta to the skillet and toss to coat evenly with the sauce. Cook for an
additional 2-3 minutes, allowing the pasta to absorb the flavors.
Divide the pasta among plates. Top each serving with fresh arugula and a generous
sprinkle of Parmesan cheese. Enjoy!
